| Summary: | Mild cognitive impairment (MCI) is largely viewed as a pre-clinical stage in the trajectory of
Alzheimer’s disease (AD) where the extent of cognitive decline is relatively mild, thus
allowing for the application of earlier, more effective treatment. Cognitive training (CT), a
form of cognitive intervention, can be subdivided into memory strategy training and
cognitive exercise. While CT has shown promise in its ability to temporarily restore cognitive
function and stimulate neuroplasticity in the MCI individual, early research in this area often
suffered from poor methodological quality. This review evaluates the efficacy of CT in MCI
based on the present research available. Additionally, results from the application of
functional magnetic resonance imaging (fMRI) and other neurobiological measures provide
evidence for CT-induced neuroplasticity in the MCI individual. However, such findings have
yet to be explored cohesively from a theoretical standpoint. This review uses the theory of
brain/cognitive reserve (Stern et al., 2018) as a basis for discussing these findings. At the
conclusion, this review finds that the present research provides better support for the
effectiveness of CT in MCI. For memory strategy training, a multidomain treatment approach
appears to be more effective in generating positive results, while in cognitive exercise, more
focused and individualised treatments tend to fair better. While present research lacks
consensus on predictors of efficacy, this review finds the largely positive results of current
studies promising, nonetheless. Potential future directions for research are discussed as well. Keywords: Cognitive Training, Memory Strategy Training, Cognitive Exercises, Mild Cognitive Impairment |
